He's been traded after winning the title with Lakers and now he's with the Denver Nuggets. I hope that he won't be traded again and he's good to stay with his team. They've got a chemistry and he's always there when he's needed on those important minutes of the game.
The Nuggets' management will make a big mistake if they don't keep their current roster for at least one more season. As for KCP, he's under contract with the Nuggets until the end of the 24/25 season. So I wouldn't worry about him because he will most likely be with the Nuggets.
Anyway, the season is officially over, and now it's offseason time. I even wonder if there will be any major trades between other teams this summer or not.
The one challenge Denver has is to make the squad deeper. This year they enjoyed perfect playoff health. While Jokic is a rock, players like MPJ or Murray have a less than perfect availability record, Uncle Jeff might as well slip just enough to become unplayable. They did a great job finding Braun in the draft, not too many rookies can credibly hold their own in the finals. As returning champions with a relatively young squad they might be able to snag a couple ring-chasing vets for the minimum.
I would guess that you need to have 2 players that can guard Jokic and the guard that plays with him at that moment, and usually people who can guard Jokic are very rare, and you need two of them, so you can switch.
The Lakers showed an interesting approach - put one big on him (Hachimura) and have another shotblocker on the court to challenge him at the basket (AD). While this lead to some turnovers, next time Jokic might be better prepared to kick it out to shooters. Also not many teams have an AD-level defender.
